Nov 6 (Reuters) – European shares opened lower on Friday, with losses across the board as a global ‌market rout gathered steam, capping a painful week ‌as investors grappled with uncertainty over AI stocks after Democrats took control ​of the US Congress.

The pan-European STOXX 600 index dropped 1.6% to 644.72 points by 0810 GMT, with benchmarks in most major regional markets also lower by more than 1% each. ‌Friday’s losses wiped ⁠out its gains for the week, and it is down about 0.2%.

The STOXX 600 index ⁠was relatively less impacted this week than its Asian and Wall Street peers, given the European index’s smaller exposure to AI ​stocks.

Media, healthcare ​and retail led broad-based ​declines, falling over 2% each.

Fears ‌that a Democrat-led Congress could seek curbs on AI data-centre spending added to concerns over weak returns, lofty valuations and debt-fueled investment.

A slowdown in AI spending could weigh on the global economy that has been propped up by ‌Big Tech investments.

Tech stocks such as ​Siltronic lost 2% and ASMI lost ​1.3%, while AI ​equipment makers such as Schneider Electric and Siemens ‌Energy were marginally lower.

On the ​earnings front, ​Teleperformance tanked 18% after cutting its full-year revenue growth outlook after weakness in the outsourcing firm’s trust and safety ​business more than ‌offset growth in its AI-powered and back-office services.
